Description

The CD74AC245 and CD74ACT245 are octal-bus transceiv-

ers that utilize the Harris Advanced CMOS Logic technology.

They are non-inverting three-state bidirectional transceiver-

buffers intended for two-way transmission from “A” bus to “B”

bus or “B” bus to “A”. The logic level present on the direction

input (DIR) determines the data direction. When the output

enable input (OE) is HIGH, the outputs are in the high-

impedance state.
